5月16日，经过近30小时的连续作业，由中交二航局四公司承建的池州长江公铁大桥3号主墩钢围堰成功封底。这不仅标志着国内最大规模矩形钢围堰工程的成功实施，更为主汛期围堰安全度汛及后续施工创造了有利条件。
据悉，此次封底的矩形钢围堰直径达到惊人的41米，总重约1.2万吨，内部结构复杂，施工难度极高。中交二航局四公司凭借丰富的施工经验和精湛的技术，克服了种种困难，确保了封底工作的顺利进行。
矩形钢围堰的成功封底，为主汛期围堰的安全度汛提供了有力保障。在主汛期，水位上涨，水流湍急，钢围堰的成功封底将有效抵御洪水侵袭，确保围堰内部的施工安全。此外，封底后的钢围堰还为后续的施工创造了有利条件。据项目负责人介绍，接下来，施工团队将进行钢围堰内部的混凝土浇筑工作，随后将启动桥墩的施工。
池州长江公铁大桥作为国家重大基础设施建设项目，其建设进展备受关注。此次矩形钢围堰的成功封底，不仅展现了我国在大型桥梁建设领域的技术实力，也为池州长江公铁大桥的顺利推进奠定了坚实基础。
未来，随着池州长江公铁大桥的建成通车，将有效缓解当地交通压力，提高交通运输效率，为区域经济发展注入强大动力。同时，该项目还将进一步完善我国长江经济带的交通基础设施，推动区域经济一体化发展。
总之，矩形钢围堰的成功封底，标志着池州长江公铁大桥建设取得了阶段性成果。在今后的施工过程中，全体建设者将继续发扬拼搏精神，严谨施工，确保池州长江公铁大桥高质量、高效率地完成，为我国桥梁建设事业再立新功。

**[Headline]:** Domestic Largest Rectangular Steel cofferdam Successfully Sealed, Laying Foundation for the Construction of Chizhou Yangtze River Rail-road Bridge
**[Text]:**
On May 16th, after nearly 30 hours of continuous operations, the No. 3 main pier steel cofferdam of the Chizhou Yangtze River Rail-road Bridge, constructed by the Fourth Company of China United Engineering Corporation (CUEC), successfully sealed its base. This not only marks the successful implementation of the largest domestic rectangular steel cofferdam project but also creates favorable conditions for the safe passage of the cofferdam during the main flood season and subsequent construction.
It is understood that the rectangular steel cofferdam, which was sealed this time, has a diameter of astonishing 41 meters, a total weight of about 12,000 tons, complex internal structures, and high construction difficulty. The Fourth Company of CUEC, with its rich construction experience and exquisite technology, overcame various difficulties to ensure the smooth progress of the sealing work.
The successful sealing of the rectangular steel cofferdam provides a strong guarantee for the safe passage of the cofferdam during the main flood season. During the main flood season, when water levels rise and currents are swift, the successful sealing of the steel cofferdam will effectively resist flood intrusions and ensure the safety of construction inside the cofferdam. In addition, the sealed cofferdam has created favorable conditions for subsequent construction. According to the project leader, the construction team will next carry out the concrete pouring work inside the steel cofferdam, followed by the start of the pier construction.
As a major national infrastructure project, the construction progress of the Chizhou Yangtze River Rail-road Bridge has been highly concerned. The successful sealing of the rectangular steel cofferdam not only shows China’s technical strength in large-scale bridge construction but also lays a solid foundation for the smooth progress of the Chizhou Yangtze River Rail-road Bridge.
In the future, with the completion and opening of the Chizhou Yangtze River Rail-road Bridge, it will effectively alleviate local traffic pressure and improve transportation efficiency, injecting strong momentum into regional economic development. At the same time, this project will also further improve the transportation infrastructure of China’s Yangtze River Economic Belt and promote the integrated development of the regional economy.
In summary, the successful sealing of the rectangular steel cofferdam marks a stage of progress in the construction of the Chizhou Yangtze River Rail-road Bridge. In the future construction process, all builders will continue to embody the fighting spirit, rigorous construction, to ensure the high-quality and high-efficiency completion of the Chizhou Yangtze River Rail-road Bridge, and to make new contributions to China’s bridge construction事业.
